PTZ/Speed Domes: Pan/tilt/zoom cameras give the surveillance operator the ability to move the camera left or right (pan); up and down (tilt); and zoom the lens closer or farther. These are relegated to surveillance situations where there is an actual live guard or surveillance specialist monitoring the images. There are cameras that have automated pan/tilt/zoom functionality where the camera is moving on a timed basis. These are many times used to cover a wide area with only one camera, or to avoid poor light conditions, such as a setting sun.
PTZ IP camera can pan, tilt, and zoom using either manual or automatic controls. This wide range of motion allows one camera to conduct surveillance from different directions and multiple angles, which makes it ideal for continuously tracking an object of interest and zooming to investigate.
